Mystras is the best thing I saw (so far) in Greece. The city from the Middle Ages is plastered against a mountain near Sparta. It's December, but it looks like fall: brown trees, fresh but chilly air, some dark clouds. The entrance gate to Mystras welcomes you in true medieval style: I knew at once I was going to like it here.
What remains of the city are its churches, a monastery, some walls and roads. The steep, cobbled streets are mostly genuine and give the feeling of actually walking there in the 14th century. The roads were narrow then, so narrow the edges of buildings were removed to leave more space for passers-by. Of course, there were shops then, markets and handicraft businesses. It would be great to be able to time travel on this spot.
The focus points are the Byzantine churches of Mystras. They were restored, both inside and outside. Frescoes, with a lot of dark blue colours, have come to the surface. The red round or octagonal roofs stand out between the now brown and green trees that surround this site. You can only walk around this scenery openmouthed.
